...and it's been fixed!
Credit to Melroy and asdfzdfj for picking it up and coding the fix in what ...7 hours?
For the wider audience, this is now fixed in the mbin code, it won't resolve here until next time @jerry updates fedia.io which could be a few days, or even week or so depending what other changes they've made and are making.
It's the same on Melroy's instance so it's an mbin issue. I'll raise an issue for it on GitHub.
Edit: I've raised it as an issue now.
Yep, same issue for me.
I don't really use Reddit anymore, but my understanding was some subreddits had crypto coins, but Reddit withdrew gold and formally started supporting these crypto tokens instead after the API exodus had happened.
